He says they are totally painless. I have not tried anything, am scared that I might make them bad.He is 7 years old,am worried please tell me what they could be and what I should do. Please.

Can you describe them to me? Are they hard or soft? What is the approximate size (use a coin as an example) are they reddish? Or brown? Are they perfectly round or no? Are they 'squishy' if poked at? Or firm.

How long have they been there?
